PLSQL delete_document 函数中的错误

Question

这是我删除文档的 PLSQL 函数。 SQLdeveloper 抱怨。我知道 VARCHAR 应该替换为 VARCHAR2，我知道这一点。还有更多的东西。包装规格绝对没问题。

FUNCTION delete_document (p_da_document_id  IN  da_documents.da_document_id%TYPE)
RETURN VARCHAR
IS

  v_delete_status VARCHAR := 'N';

BEGIN

  DELETE FROM da_document_key_values
  WHERE da_document_id = p_da_document_id;

  DELETE FROM da_document_tags
  WHERE da_document_id = p_da_document_id;

  DELETE FROM da_documents
  WHERE da_document_id = p_da_document_id;

  COMMIT;

  SELECT COUNT(*) AS doc_count
  FROM   da_documents
  WHERE  da_document_id = p_da_document_id;

  IF (doc_count = 0) THEN
    v_delete_status := 'Y';
  END IF;

RETURN v_delete_status;

END delete_document;

Answer 1

刚刚发现上面的一个程序没有正确结束。结尾;失踪。我的错。
